Benefits of technology

"The present invention provides an improved method and system for updating an archive of a computer file to reduce or eliminate problems and disadvantages associated with previous systems and methods. The method involves selecting one of a plurality of comparators based on user and / or system input, conditions or criteria to optimize data store, data transfer or other archive resources. The comparators include a first comparison method where the file is compared to an archive of the file and a second comparison method where a set of tokens statistically representative of the file is computed and compared to a set of tokens statistically representative of the archive of the file. The method also involves carrying out the preferred comparison method to generate indicia of differences between the file and the archive of the file for updating the archive of the file. The technical effect of this invention is to provide a more efficient and effective way for updating computer file archives."

Problems solved by technology

Conventional comparators and differentiating systems used in file archiving systems suffer disadvantages in that they are process or memory intensive and inflexible.
As a result, they are unsuitable for some systems, applications and / or conditions.

Embodiment Construction

[0017]FIG. 1 illustrates a client computer 100 connected to a server. computer 300 via an Internet or other network connection 200 to update file archives on server computer 300. Client and server computers 100 and 300 can be. any suitable types of conventional computers such as a laptop, a personal computer (PC), a desktop PC, a handheld PC, and the like, or computers specially configured for a specific purpose. In one embodiment for example, client computer 100 may be a laptop connected to a server computer 300 through phone lines from a hotel room. In another embodiment, client computer 100 may be specially configured, incorporated into medical diagnostic equipment, and connected to a central server computer 200 via the Internet for archiving valuable information. As records are updated on a particular client computer 100 throughout a diagnostic process or a series of processes, archives of the records can be updated on the central server computer using the present invention. It ...

Abstract

A method and system for updating an archive of a computer file to reflect changes made to the file includes selecting one of a plurality of comparison methods as a preferred comparison method. The comparison methods include a first comparison method wherein the file is compared to an archive of the file and a second comparison method wherein a first set of tokens statistically representative of the file is computed and compared to a second set of tokens statistically representative of the archive of the file. The method further includes carrying out the preferred comparison method to generate indicia of differences between the file and the archive of the file for updating the archive of the file.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application Ser. No. 60 / 186,137 filed Mar. 1, 2000 and entitled “File Archiving System”, which is hereby incorporated along with its referenced materials by reference.TECHNICAL FIELD OF THE INVENTION[0002]This invention relates generally to the field of file archiving, and more particularly to a method and system for updating an archive of a computer file.BACKGROUND OF THE INVENTION[0003]File archiving systems backup computer files to protect against data loss. As files are modified over time, a comparator differentiates between new and archived file versions for the purpose of updating the archived versions. Known comparators include revision control engines and exclusive-or (XOR) processes.[0004]Conventional comparators and differentiating systems used in file archiving systems suffer disadvantages in that they are process or memory intensive and inflexible. As a result, they are unsuitable for some sys...
